Description

Technical Field

[0001] The invention relates to the technical field of wire stripping, and in particular to a stripping machine suitable for wires of different thicknesses. Background Art

[0002] Wires are conductors that transmit electrical energy. They are classified into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires, and various profiles (such as profiled wires, busbars, copper bars, aluminum bars, etc.). They should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, and solvent resistance. Different properties can be obtained by selecting different insulating materials.

[0003] Wire stripping machine is a kind of equipment specially used for stripping the insulation layer of wires. It is widely used in wire and cable manufacturing, maintenance and recycling industries. First, insert the wire into the stripping machine and make sure it is in the correct position and fixed. Then gently pull the wire through the blade and make sure that the blade is in close contact with the insulation layer. Finally, start the stripping machine. The blade will automatically and slowly strip the insulation layer. However, the stripped insulation layer needs to be manually torn off later, which is very troublesome and not conducive to the automated production rhythm. Summary of the invention

The blade will automatically and slowly peel off the insulation layer, but the peeled insulation layer needs to be manually torn off later, which is very troublesome and not conducive to the automated production rhythm.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example:

[0033] See also Figure 1-Figure 7 The present invention provides a technical solution: a stripping machine suitable for wires of different thicknesses, comprising:

[0034] The operating body 1 includes a driving unit 11, and the driving unit 11 is slidably connected to a clamping member 13 connected to the outer end of an external electric wire through an electric track 12 arranged on the outer side thereof;

[0035] The stripping part 2 includes a ring sleeve 21, which is connected to the output end of the driving unit 11 through a connecting frame 22 arranged on its side, and a blade member 23 that can be used for stripping external wires is arranged on the side of the ring sleeve 21 away from the driving unit 11;

[0036] Among them, the clamping member 13 includes an electric slider 131, the lower surface of the electric slider 131 slides with the upper surface of the electric track 12, the electric slider 131 is rotatably connected to a ring plate 133 through a circular guide rail 132 set on its top, and the ring plate 133 is connected to a clamping block 135 through an electric push rod 134 set on its inner wall.

[0037] A gear ring 1331 is fixedly connected to the side of the ring plate 133 away from the ring sleeve 21 , a servo motor 1311 is fixedly connected to the upper surface of the electric slider 131 , and a driving gear 1332 meshing with the gear ring 1331 is fixedly connected to the output end of the servo motor 1311 .

[0038] Two clamping blocks 135 are provided and are symmetrically distributed with the external electric wire as the center. The diameter of the clamping block 135 is much larger than the diameter of the external electric wire. A built-in cavity 1351 is provided inside the clamping block 135. A T-block 1352 is slidably connected to the inner wall of the built-in cavity 1351, and a return spring 1353 connected to the inner wall of the built-in cavity 1351 is provided on the outer surface of the T-block 1352.

[0039] The T-block 1352 adopts a magnetic design, and the inner wall of the built-in cavity 1351 is fixedly connected with an electromagnetic block 1354 magnetically connected to the T-block 1352. The side of the T-block 1352 away from the electromagnetic block 1354 adopts an arc surface design, and the arc surface of the T-block 1352 is provided with a plurality of groups of thorn-like fine teeth 1355.

[0040] An electric retractor 211 is arranged inside the ring sleeve 21 . The electric retractor 211 is rotatably mounted with balls 213 that fit with external wires via a universal ball bearing 212 arranged at its output end. The balls 213 are arranged in six groups and are evenly distributed in the space surrounded by the ring sleeve 21 .

[0041] The blade member 23 includes a support 231, the outer surface of the support 231 is fixedly connected to the side of the ring sleeve 21 through a bracket, the inner rotation of the support 231 is connected to a shaft rod 232, and the shaft rod 232 is fixedly connected to one end close to the external wire, and the output end of the micro precision push rod 233 is fixedly connected to a blade 234.

[0042] The end of the shaft 232 away from the micro precision push rod 233 is fixedly connected to a driven gear 235 , the circumferential outer surface of the ring sleeve 21 is fixedly connected to an electric push cylinder 236 , and the output end of the electric push cylinder 236 is fixedly connected to a toothed plate 237 meshing with the driven gear 235 .

[0043] refer to Figure 1-7 The traditional stripping process is: first insert the wire into the stripping machine, and make sure it is in the correct position and fixed, then gently pull the wire to pass the blade, and make sure the blade is in close contact with the insulation layer, and finally start the stripping machine. The blade will automatically and slowly strip the insulation layer, but the stripped insulation layer needs to be torn off manually later, which is very troublesome and not conducive to automated production rhythm. In order to overcome the above defects, this application designs a stripping machine that can automatically cut off the stripped ends of wires of different thicknesses.

[0044] In practical applications, wire fixation:

[0045] Prepare the wire to be stripped, and pass the stripped end through the drive unit 11 and the ring 21 in sequence until it is inserted between the adjacent clamping blocks 135. Then, start the electric push rod 134 on the clamping member 13, and its output end drives the clamping block 135 to move toward the side of the wire, and the two groups of clamping blocks 135 clamp the outer surface of the wire end. Since the diameter of the clamping block 135 is much larger than the diameter of the external wire, the space enclosed by the two groups of clamping blocks 135 can meet the requirements of a certain range and fix wires of different thicknesses.

[0046] Next, the electric retractor 211 on the stripping part 2 is started, driving the universal ball bearing 212 and the balls 213 to move synchronously toward one side of the wire until the six groups of balls 213 are wrapped around the outer surface of the wire circumference, thereby achieving "wrapping limit" on the wire, which is not only conducive to the rapid stripping of the subsequent blade 23, but also prevents the wire from sliding and deviating.

[0047] In practical applications, wire stripping:

[0048] Next, the micro precision push rod 233 on the blade 23 is started. The micro precision push rod 233 has a high-precision positioning and adjustment function, which can meet the requirements of precision operation. Through the precise control of the drive control system and the transmission mechanism, the micro precision push rod 233 can achieve micron-level height adjustment. At the same time, with the corresponding measurement and feedback device, the position can be monitored and precisely adjusted in real time. The micro precision push rod 233 drives the blade 234 to insert into the insulation layer of the wire. Finally, the electric track 12 drives the electric slider 131 to slide on its upper surface, driving the circular guide 132, the ring plate 133, the gear ring 1331, the driving gear 1332, the electric push rod 134, the clamping block 135 and the end of the wire to move forward synchronously, pulling the wire (initially, the cutting end of the blade 234 is located at the starting point of the end of the wire). Under the action of the blade 234, the blade 234 automatically cuts the insulation layer. Since there are two groups of blades 234, the upper and lower blades are cut synchronously, and the insulation layer is divided into two until the electric slider 131 slides to the preset position.

[0049] Furthermore, the electric push cylinder 236 is started, and its output end drives the tooth plate 237 to move forward, and the tooth plate 237 meshes to drive the driven gear 235 to rotate (the upper driven gear 235 rotates 90 degrees clockwise, and the lower driven gear 235 rotates 90 degrees counterclockwise), and the upper and lower sets of blades 234 rotate 90 degrees (in opposite directions) respectively. The driving motor inside the driving unit 11 drives the connecting frame 22, the ring sleeve 21 and the blade member 23 to rotate clockwise, and the upper and lower sets of blades 234 realize circular cutting of the cutting end of the insulation layer (the cutting position remains unchanged), so that the insulation layer divided into two can be quickly separated from the exposed battery core, eliminating the trouble of manual tearing.

[0050] It is worth noting that, in the present application, the clamping member 13 and the peeling part 2 are used in combination, which has the following advantages:

[0051] Advantage 1: The diameter of the clamp 135 is much larger than the diameter of the external wire, which can meet the requirements of fixing wires of different thicknesses within a certain range. At the same time, the electric retractor 211 drives the universal ball bearing 212 and the balls 213 to move synchronously toward one side of the wire until the six groups of balls 213 are wrapped around the outer surface of the wire circumference, which can also meet the requirements of "wrapping limit" for wires of different thicknesses within a certain range.

[0052] Advantage 2: Since there are two sets of blades 234, they can cut synchronously from top to bottom to divide the insulating layer into two. At the same time, the electric push cylinder 236 drives the tooth plate 237 to move forward, and the tooth plate 237 drives the driven gear 235 to rotate. The upper driven gear 235 rotates 90 degrees clockwise, and the lower driven gear 235 rotates 90 degrees counterclockwise. The upper and lower sets of blades 234 rotate 90 degrees (in opposite directions) respectively to adjust the cutting direction of the blades 234 at the origin position. Subsequently, the two sets of blades 234 rotate clockwise to achieve circular cutting of the cutting end of the insulating layer, so that the insulating layer divided into two can be quickly separated from the exposed battery cell, eliminating the trouble of manual tearing.

[0053] Advantage three: First, the six groups of balls 213 are wrapped around the outer surface of the wire, achieving "wrapping limit" for wires of different thicknesses. Second, when the upper and lower groups of blades 234 perform circular cutting, in order to improve cutting accuracy, the six groups of balls 213 always fit the outer surface of the wire, which can not only achieve horizontal rolling, but also vertical rolling. When the blade 234 performs circular cutting, the six groups of balls 213 move synchronously with it (one end of the wire is still fixed by the clamping member 13), ensuring that the central axis of the wire remains unchanged (avoiding inconsistent cutting depth and damaging the battery core), facilitating the blade member 23 to quickly perform circular cutting, and reducing rotational friction.

[0054] Advantage 4: In order to further increase the friction between the clamp block 135 and the wire and prevent the wire end from being detached during the pulling process, the present application is also provided with a T-block 1352, a reset spring 1353, an electromagnetic block 1354, and thorn-like fine teeth 1355. When the two sets of clamp blocks 135 clamp the wire ends, the electromagnetic block 1354 is started, and the magnetic force generated drives the T-block 1352 to slide outward along the inner wall of the built-in cavity 1351 (the reset spring 1353 is elastically deformed under tension), driving the thorn-like fine teeth 1355 to insert into the insulating layer of the wire end, greatly increasing the friction between the clamp block 135 and the wire. At the same time, the T-block 1352 is set in the middle of the clamp block 135 to meet the clamping requirements of wires of different thicknesses.

[0055] Advantage five: after the circumferential cutting of the wire insulation layer is completed, the two groups of clamps 135 will also detach from the stripped wire ends. At the same time, the insulation layer that is split into two will follow the thorn-like fine teeth 1355 to synchronously detach from the exposed battery core. In order to quickly separate the insulation layer that is split into two and the thorn-like fine teeth 1355, on the one hand, the electromagnetic block 1354 can be powered off, and under the elastic force of the reset spring 1353, the T-block 1352 and the thorn-like fine teeth 1355 are driven to reset and slide into the built-in cavity 1351, so as to quickly separate the insulation layer and the thorn-like fine teeth 1355 after stripping; on the other hand, the servo motor 1311 is started, and its output end drives the drive gear 1332 to drive the T-block 1352 and the thorn-like fine teeth 1355 to reset and slide into the built-in cavity 1351, so as to quickly separate the stripped insulation layer and the thorn-like fine teeth 135 .... The toothed ring 1331 rotates, driving the ring plate 133, the electric push rod 134, the clamping block 135, the T-block 1352 and the thorn-like fine teeth 1355 to rotate synchronously. The thorn-like fine teeth 1355 drive the peeled insulation layer to rotate synchronously, so that it can quickly detach from the battery cell. At the same time, under the action of centrifugal force, the T-block 1352 slides into the built-in cavity 1351, so that the thorn-like fine teeth 1355 and the peeled insulation layer are quickly separated, and the peeled insulation layer is rotated and thrown out in a small range (a protective net is provided on the outside of the device of this application).
